The VT4887A is a rugged, compact and
lightweight enclosure housing two 8"
woofers, four 4" midrange radiators, and
two high frequency compression drivers.
VERTEC’s advanced components provide
extremely high power-to-weight ratio.
Enclosure features foam-backed low
frequency grilles, dense protective foam
inserts for midrange apertures and fine steel
mesh grille to protect high-frequency
apertures. Speaker cones are treated with
weather-resistant compounds. VERTEC arrays
are rigid for maximum support strength, yet
flexible in design and application. Rigging
tubes made of hard-black anodized 6061-T6
Aluminum. Hinge bars made from
premium-grade chromoly alloy steel, with
epoxy powder coating over plated surfaces.
Plated hinge pins and stainless steel quickrelease
pin lanyards to resist corrosion and
weather damage. The VT4887A’s
suspension hardware relies on quick-release
pins and end-mounted metal tubes to
couple adjacent VT4887A’s together.
Enclosure ships with integral front and rear
hinge bar set. Protective grille cover/wheel
board and soft cover ensure handy
transport for rough road conditions,
(purchased separately as VT4887-ACC).
